Nov. v3, 1931- G. A. SCHWARTZEL BOOK HANGER Filed Dec. 9, 1929 PatentedNov." 3,f 1931 UNITED STATES PATENT OFFICE GUSTAV A. SGHWARTZEL, 'OF ST.LOUIS, MISSOURI BOOK HANGER Application filed December 9, 1929. SerialNo. 412,773.

pMy invention i'elation to improvements in book hangers, that is,devices that may bequickly attached'to a book of reference such as acatalog or telephone book for the purpose of suspending the book from ahook for easyaccess. The invention consists in the novel features ofconstruction more fully set forth in the specification and pointed outin the claims. 7

The object of the invention is to provide a hangerthat may be quicklyattached to and detached from the book, one that will not damage thebook,and one that is simple but positive in its operation. Further andother advantages will be better. apparent from a detailed description ofthe invention in connection with the accompanying drawings, in

Fig. 1 is a perspective view of a book suspended by means of my improvedhanger; Fig. 2 is a side elevation of the hanger in operative positionwith a part broken away; Fig. 3 is a cross-sectional detail takenon theline 33 of Fig. 2; and Fig. 4 is a side eleva tion of the hanger withits cooperative members in open or inoperative position.

Referring to the drawings, H represents my improved hanger comprisingcooperative components 1 and 2 pivotally connected by means of a'hollowrivet 3 serving as a hinge. The component 1 is U-shaped in cross-section(Fig. 3), and the sides a, 0; thereof are both provided with taperingslots 5, b which are narrower at their closed ends a and flare outwardlyat their open ends cl. The component 2 is essentially a blade hinged atits lower end, as above described, to the member 1 between the sides a,0; thereof, the part i of said blade adjacent the hinge 3 being widenedinwardly to form a cam 4', and the upper part of the blade being widenedto form a handle 5 in which isthe opening or eye 6 for receiving a hook7 from which a book B,.engaged by my hanger H, may be suspended. Theblade 2 is of a thickness that it will just enter the space 8 betweenthe sides a, a of component 1. It will be observed that the sides of thecam 4 are slightly beveled as shown at e, 6 (Figs. 2 and 3) for thepurpose of more readily forcing the back f of the book B into'the spacesand tightly gripping the same when the components 1 and 2 of the hangerare in operative or closed position. To prevent said components 1 and 2from being easily separated, a hole 9 is provided in the blade 2 and themetal 1 of the walls a is punched inwardly to provide a detent 8 whichenters the hole 9 when the components '1 and 2 are in closed position.When it is desired to release the hook B from the hanger H, thecomponent 2 is merely swung to open position (as shown in Fig. 4;) sothat the cam 4 will release the back f of the book whereupon the backwill easily slip out of the slot 6.

Having described my invention, I claim:

1. A book hanger comprising a U-shaped component and a blade componenthinged between the sides of said U-shaped component,

said sides having open slots to receive the back of the book, and permitthe sides to enter between the sheets thereof means on the bladecomponent for cooperating with the slots of the U-shaped component togrip said book back when the components are in closed position and ahandle at one end of the blade.

2. A book hanger comprising a U-shaped component and a blade componenthinged between the sides of said U-shaped component, said sides havingopen slots to receive a part of the book, a cam on the blade componentadapted to cooperate with the slots on the U-shaped component to gripsaid book part when the components are in closed position and a handleat one end of the blade.

3. A book hanger comprising a U-shaped component and a blade componenthinged between the sides of said U-shaped component, said sides havingopen slots to receive a part of the book, means on the blade componentfor cooperating with the slots of the U-shaped component to grip saidbook part when the components are in closed position, means for holdingthe components in closed position and a handle at the upper end of theblade.

4. A book hanger comprising cooperative components, one of whichcomprises a holding sheath having sides in closely spaced relation, theother component comprising a blade pivotally mountedbetween the sides ofthe sheath and receivable therein, alining longitudinally disposed slotsin the sides of the sheath adapted to be traversed by apart of the book,and means on theblade for gripping the book part when the blade ishoused in the sheath.

In testimony whereof I hereunto afiix my signature.
